Elaine is painting a fence. She knows that she needs 1 gallon of paint for each 10 feet of fencing. The fencing will enclose a r

Tcecarenko [31]

There are 2 walls that are 9 feet each and then 2 walls that are 6 feet each. Adding those up will give you 30 feet of fencing. If you need 1 gallon for every 10 feet and there are 30 feet of fencing, that would mean that you need 3 gallons of paint.

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

Sophie [7]

Answer:

the experimental probability is 70%

Step-by-step explanation:

PLEASE HELP, TIMEDThe table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they have.

What is the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings?

To the nearest whole percent, the experimental probability is

a. 65%.

b. 70%

c. 75%

d. 80%

We are given to find

the experimental probability that a 10th-grade student chosen at random has at least one, but no more than two, siblings

we know that

probability = ( number of favourable outcomes)/ ( total possible outcomes)

a 10th-grade student chosen at random has at least one, but no more than two, siblings

so, there can be one or two siblings

so, total number of such students =18+10=28

Number of favourable outcomes =28

total number of students =4+18+10+8=40

so, total favourable outcomes =40

now, we can find probability

$p=\frac{28}{40}\\\\p=\frac{28}{40}\times 100\\\\p=70$

So,

Therefore, the experimental probability is 70%

Function g can be thought of as a scaled version of f(x)=x^2

labwork [276]

Answer:

g(x)=2x^2

Step-by-step explanation:

If you look at (1,1) for the blue function then (2,2) for g(x), you can kind of see that it is scaled by 2 (meaning its just twice as big). In another case you can see the blue function passing through (2,4), which matches with the point given to you for g(x), (4,8), which is twice as big.
